Out of the box, your voicemail will work with default generic prompts. You can easily check the vm from your phone or app. If you would like to get the voicemail to your email inbox, you can also configure this in your profile. It will attach the voicemail as an audio file and will send you the transcript of the message like what you see below.
Review the following documentation and reach out if you have questions.
